Hello! Looking for a transmission for my 1970 Mustang. Built 408w running 550hp to the wheels, though built for a 200 shot of Nitrous/boost; the old Fmx finally went and I'm looking for an overdrive trans, looking to buy asap. Anyone with a 4r70w, tko (500/600 is fine), T56, etc. setup looking to sell, let me know! I'm in Washington, but will pay for shipping if its farther.
